Description
Technical field
The present invention relates to the catalyst that a kind of hydrogenolysis of glycerin prepares 1,3-PD, specially WOxCarrier loaded active group
Divide molybdenum oxide and platinum.
The invention is related to the preparation method and applications of above-mentioned catalyst, specially prepares WO using solvent thermal processx, adopt
Active component platinum and molybdenum are supported with two step infusion processes, and are investigated under different preparation conditions the catalyst and prepared 1 in hydrogenolysis of glycerin,
Activity and selectivity in 3-propanediol.
Technical background
With the rapid development of biodiesel, the by-product glycerin produced in biodiesel process is excessive, converts sweet
Oil preparation high value chemicals becomes the effective means for promoting Biodiesel economy.Glycerol can be raw by hydrogenolysis
At 1,3-PD, 1,2-PD etc., wherein 1,3-PD is the important of production polypropylene terephthalate (PTT)
Monomer.PTT is a kind of new type polyester fiber with biodegradability, it overcomes polyethylene terephthalate
(PET) too hard and too soft polybutylene terephthalate (PBT) (PBT) disadvantage, while there is excellent resilience, chromatophilia is raw
Object degradability etc., thus there is huge development potentiality in industries such as carpet, Textile Engineering plastics.The work of 1,3- propylene glycol at present
Industry production method has the oxirane carbonyl hydrogenation method of Shell company and the acrolein hydration of Degussa and Dupont company
Hydrogenation method.
Oxirane carbonyl hydrogenation method (Chinese patent CN1201407A) using ethylene oxide under cobalt-base catalyst with
Synthesis gas generates 3-HPA, then 3-HPA and hydrogen are hydrogenated to 1,3-PD under hydrogenation catalyst effect
Method.Acrolein hydration method (Chinese patent CN93114516.3) is taken off under solid acid catalyst using gaseous state glycerol hydrate
Water generates methacrylaldehyde, and the methacrylaldehyde of generation is lauched symphysis into 3-HPA, the 3- hydroxyl third of generation in acidic catalyst effect
Aldehyde is under conventional hydrogenation catalyst plus hydrogen prepares 1,3-PD, while by-product 1,2-PD.
Above-mentioned industrial manufacture process is complicated, and environmental pollution is serious, and gained 1,3-PD contains impurity, need to further purify
Processing.
Document (Appl.Microbiol.Biotechnol.1992,36,592-597) reports a kind of use
The method that Clostridiurn strain bio conversion prepares 1,3-PD can turn the glycerite of 110g/l after 29h
Change obtains the 1,3-PD of 56g/l, and this method is influenced by biological metabolic activities, and production efficiency is low, and due to
Production concentration is low, and energy consumption needed for purifies and separates 1,3-PD is also very high.
Document (Catal.Commun.2008,9,1360-1363) reports one kind in 1,3- dimethyl-2-imidazolinone
For under solvent, the method that hydrogenolysis of glycerin prepares 1,3-PD, the yield of the method 1,3-PD is 24%.
The Tomishige seminar of Japan reports the Rh/SiO of Re modification2And Ir/SiO2Catalyst, author is in Ir-Re/
SiO2Fluid sulphuric acid (H is added under catalyst action+/ Re=1), initial hydrogen pressure 8MPa, at 120 DEG C of reaction temperature, 20%
After reacting 36h in glycerine water solution, the yield for having obtained 1,3-PD is up to 38.0%.Subsequent literature (Journal of
Molecular Catalysis A:Chemical.2014,388,177-187) third auxiliary agent especially Ru is also reported to sweet
The facilitation that oily hydrogenolysis prepares 1,3- propylene glycol is most obvious.
The Jinho Oh of South Korea reports the ZrO that Pt is supported on sulfuric acid acidification2On, using DMI as reaction medium, in hydrogen
Initial pressure is 7.3MPa, reacts at 170 DEG C of reaction temperature and has obtained the yield of 1,3-PD for 24 hours and be up to 55.6%.
Organic solvent is used in above-mentioned reaction as reaction medium, and the method for used adding liquid acid, no
Meet the requirement of Green Chemistry.
The direct hydrogenolysis of glycerol prepares 1,3-PD and has obtained very big concern in recent years, because its simple process, raw material are honest and clean
Valence.Document (Chin.J.Catal.2012,33:1257-1261) is although report a kind of mesoporous WO of simple Pt/3It is directly used in
The catalyst of hydrogenolysis of glycerin 1,3-PD, but the whole yield of 1,3-PD is still lower.So far, document
It is 100% and the best performance of selectivity up to 66% that (ChemSusChem2013,6,1345-1347), which reports conversion ratio,
Pt/WOx/ AlOOH catalyst system.But be converted into the unit noble metal catalyst unit time acquisition 1,3-PD yield and
Speech, is still in reduced levels.Simultaneously also have document (Journal of Molecular Catalysis A:
Chemical.2015,398,391-398) report WOxTo Pt/Al2O3Facilitation.Document (Chem.Lett.2012,
41,1720--1722) report AlOxTo Pt Nanoparticles/WO3Make in the promotion of hydrogenolysis of glycerin 1,3- propylene glycol
With.Even author has also investigated MoOxTo Pt Nanoparticles/WO3Facilitation, unfortunately, in this document,
MoOxAddition so that entire catalyst is not exhibited any activity instead.The facilitation and WO of possible auxiliary agentxStructure and Pt
Dispersibility has substantial connection.Entire catalyst system is made a general survey of, research hotspot is concentrated mainly on Pt/W/Al at present2O3System and towards auxiliary agent
Addition direction is developed.Either improve the pattern of each species, content or crystalline structure are arranged auxiliary agent type, there are different journeys
The raising of the 1,3-PD yield of degree, reaction dissolvent are also generally fixed to the water phase condition of environmental protection, but all also keep substantially
In higher pressure (5MPa is in the majority, highest 8MPa) and higher temperature (180-200 DEG C).In order to make the direct hydrogenolysis preparation of glycerol
1,3-PD reaction condition is milder, and yield further increases, it is necessary to new catalysis is further developed on the basis of existing
System.
